Apache Camel 错误启动包

Question

学习Apache Camel- 尝试在 jboss-fuse-6.1.0.redhat-379.

上部署应用程序

POM如下

                    <artifactId>camel-maven-plugin</artifactId>

                </plugin>
            </plugins>
        </build>
    </project>

在数据库配置文件中配置了以下内容

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver" />
        <property name="url" value="jdbc:mysql://localhost/univ" />
        <property name="username" value="root" />
        <property name="password" value="pass" />
</bean>


<bean id="sqlComponent"                                       
      class="org.apache.camel.component.sql.SqlComponent">
      <property name="dataSource" ref="dataSource" />
</bean>

并在路由中调用了 sql 组件

<to uri="sqlComponent:{{sql.insertData}}" />

在保险丝上部署时得到-

Error executing command: Error starting bundles:
    Unable to start bundle 255: Unresolved constraint in bundle  
com.dao.came
lDAO [255]: Unable to resolve 255.0: missing requirement [255.0]

kage; (&(osgi.wiring.package=org.apache.camel.component.sql)

requirement [253.
0] osgi.wiring.package; (&(osgi.wiring.package=org.apache.camel) 
(version>=2.13.0
)(!(version>=3.0.0)))]

已经使用 wrap:install 安装了 jar，仍然出现上述错误

请大家帮我想想办法。谢谢

Answer 1

尝试导入丢失的包：

    <plugin>
        <groupId>org.apache.felix</groupId>
        <artifactId>maven-bundle-plugin</artifactId>
        <version>2.3.7</version>
        <extensions>true</extensions>
        <configuration>
            <instructions>
                <Bundle-SymbolicName>${project.artifactId}</Bundle-SymbolicName>
                <Bundle-Description>${project.description}</Bundle-Description>
                <Import-Package>
                    *,
                    org.apache.camel.osgi,
                    org.apache.camel.component.sql,
                    org.apache.camel
                </Import-Package>
            </instructions>
        </configuration>
    </plugin>

并且必须安装 camel-sql 功能。

更新：

Have installed the jars using wrap:install

您只需为数据库驱动程序执行此操作，所有其他驱动程序必须由功能安装。

>    <bean id="sqlComponent"                                       
>          class="org.apache.camel.component.sql.SqlComponent">
>          <property name="dataSource" ref="dataSource" />    
>    </bean>

可以更简单地实现：

<to uri="sql:{{sql.insertData}}?dataSource=dataSource" />

请检查您安装在 jboss fuse 服务器上的 Camel 版本，它必须与您项目中指定的版本相匹配。

Answer 2

您需要在 Jboss 保险丝中安装 Mysql 连接器。对于安装，我们需要在 Fuse 终端中运行以下语句。

osgi:install -s wrap:mvn:mysql/mysql-connector-java/5.1.39

可以根据您使用的 mysql 连接器更改版本。

安装后一次。尝试运行你的项目。
